WebKnow how to obtain the estimate MSE of the unknown population variance σ 2 using statistical software. Know that the coefficient of determination (r 2) and the correlation coefficient (r) are measures of linear association. That is, they can be 0 even if there is perfect nonlinear association. Know how to interpret the r 2 value. WebThis equation can either be seen in a dialogue box and/or shown on your graph. How well this equation describes the data (the 'fit'), is expressed as a correlation coefficient, R 2 (R-squared). The closer R 2 is to 1.00, the better the fit. This too can be calculated and displayed in the graph.
